The other two unused subdevices are for calibration, which the labpc+ doesn't support (except with a screwdriver). There is no analog output command support because I chose not to add it. This is because the hardware doesn't really support waveform analog output. There is only a 1 sample analog output buffer, and worse still the board doesn't provide any means to detect when the output buffer has underrun. - -- Frank -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) Comment: For info see http://www.gnupg.org iD8DBQFAHDLw5vihyNWuA4URAg6HAJ47JGXoR9rhrcQH6PJPtxmJxCQFcQCgrfjJ kPtZZ6FPGFz8yQyJjeGoN5M= =ojXM -----END PGP SIGNATURE-----
